Has improved performance for mission-critical workloads and enabled seamless non-disruptive upgrades
The availability is 99.99%, which is the main factor any customer would need because their data should be available whenever they want to access it. This is one main critical thing. It is very easy to upgrade since Pure Storage FlashArray handles it well. Everything is non-disruptive now; previously, there were forklift shifts, but now that is not the case. Pure Storage FlashArray says no to forklift upgrades. Usually hardware requires downtime, but Pure Storage FlashArray has improved their footprint so that they are not asking for downtime; everything is just a non-disruptive activity, which is why customers are more inclined towards Pure Storage FlashArray. Customers want more of the models in their environment due to the performance they are giving, and everything is in one Pure1 Array console where we can view all the models on one page or just an orchestration tool. You don't miss anything; you have replication, notifications about replication, and details about which host groups replication is happening in and if that replication is successful or failed. On a daily basis, our purpose is to create volumes for infrastructure; our daily activities include creating volumes and mapping them to the host, doing any migrations from a VM, clearing the data stores, and carving the volumes to those VMs. One key factor is the data compression with a ratio of 5:1, focusing on space efficiency, inline deduplication, and the compression Pure Storage FlashArray works on; that is a major factor we can suggest to any customer. Analytical capabilities are crucial. Daily, we check the throughput and consumption, and Pure Storage FlashArray provides predictions for one year regarding usage. This prediction helps plan updates well ahead. For support, we just raise a case, and they follow up and get it done. There is also AI readiness, but with the model R2, we don't have much of that AI readiness. For others, we do have AI readiness that predicts capacity based on daily or monthly trends, enabling us to analyze how much space we need or if we need to expand the disk shelf. From an operational point of view, a good feature is that if you accidentally delete a volume, it will be retained in the destroyed state for the next twenty-four hours, which is not the same with any other vendor. I have worked in this storage domain for the past fifteen years, and this option is remarkable, benefiting any L1 or L2 engineer. Additionally, from a compliance perspective, Pure Storage FlashArray has REST APIs enabled. I have not explored automation much, but from a security standpoint, it is strong with encryption data. If you want to automate, you can easily integrate with all clouds and explore Pure Cloud for scheduling workloads, including volume creation. Customers find benefit in Pure Storage FlashArray's single management pane of glass due to the dual controller and active-active setup. If one of the controllers goes down, all workloads automatically shift to the other controller, ensuring their data is safe and accessible at all times. This is a highlighted feature that any customer desires because their data should always be accessible. For SAN workloads, we use Pure Storage FlashArray because for SAN FC fiber channel, we don't use it; we use NetApp for NAS activities. We have clearly split this, so SAN is for mission-critical applications, while network-attached storage handles file systems. This architecture helps us maximize the benefit from Pure Storage FlashArray due to the significant workloads from this giant retail client. From a footprint and energy consumption perspective, you can see energy consumption from the Pure1 storage portal on a daily basis, and it is very compact. The three models we use consume only three units, which is quite low. From a footprint and data center perspective, it doesn't occupy much space. As everything moves to cloud, there are requirements to avoid excess spending on data centers, and Pure Storage FlashArray is efficient in energy consumption and is environmentally friendly.

Performance and interface improve data processing speeds but require complex configuration
The most valuable features of VMAX are its performance and GUI interface. We have seen significant improvements in technology over the last four to five years. The snap feature, along with deduplication, has notably enhanced our data processing speeds. We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution.

Cloud data management that achieves cost efficiency with advanced data protection features
I am currently using Nasuni for seismic data. We have a huge data size, and we want to reduce costs. Nasuni acts as a caching solution, so we put some data into the cache, and the rest goes to the blob, which helps us save on costs. We use it for applications like Petrol and Tech Log, where 3D…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"After the implementation, the time to run the process was reduced to minutes and it did not require any manual intervention from our DBAs."
"Provides fast access and is user-friendly."
"While all these products have their own uses, Pure Storage FlashArray is in a market of its own."
"Once we solved the data reduction and what Pure does we were hooked."
"Pure Storage is seen as a visionary company with leading edge technology."
"The performance and the ever-growing maintenance are the most valuable features of this solution."
"The performance levels and the storage have improved my organization because we're a 95% virtualized environment and we're able to allocate resources as needed and manage our whole infrastructure that way."
"The cost of Pure FlashArray is a bit high compared to peers, but its sustainability and features justify the price."
"The ransomware protection feature is housed in a separate unit, specifically addressing the top twenty most critical threats."
"The snapshot feature has been precious for our testing processes, application development, and managing testing environments due to its efficiency and ease of use."
"The most valuable features of VMAX are its performance and GUI interface."
"The product's initial setup phase was good."
"We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution."
"It works very well."
"Overall, it has been straightforward and we're very pleased with the Nasuni system."
"The most important feature is that things are backed up automatically in AWS. We have a lot of remote sites where there is a tiny server onsite and, in a lot of cases, we really don't have to back them up because the data is automatically copied to AWS. The cloud replication is the most useful functionality for us."
"My advice to others looking into implementing Nasuni is to go for it; it's very simple to set up, very simple to configure, and easy to manage."
"I can't say anything other than good things about it."
"The global file locking feature is valuable. The ability to quickly deploy new sites is also valuable."
"The system has so far been doing an awesome job and working as advertised."
"I would recommend Nasuni because it's a proven product that has delivered results for us even in the worst-case scenario. If you're still using a traditional cloud solution like native Azure products, you are still susceptible to human error. Also, you would need to architect your backup and DR solutions, then integrate, maintain, and administer them."
"We have absolutely seen an ROI, and we are super happy with our ROI."
 

Cons

"Most of our upgrades have not been as smooth as they should have been."
"I would prefer that they lower their pricing."
"The price is too high."
"I would like to see data tiering to AWS."
"For scalability, I rate it a six out of ten. We reach a limit. We never reached this limit, however, the architecture allows you to go until a certain size, and after that, you have to buy another array."
"Automation could be simplified."
"I would love to see a true one click upgrade solution. Right now, you have to click and schedule an appointment with Pure Storage to be able to upgrade. I would love for it to automatically download, install, and fall-over every controller as it updates."
"The primary drawback is the cost, which can be prohibitive for small configurations."
"There is room for improvement in the centralized administration."
"Improvements are needed in both partition recovery and scalability."
"We encountered some challenges during large data migrations that could be addressed for smoother transitions."
"The scalability of VMAX is somewhat limited, especially in terms of cache scalability. We've had to procure additional engines to address this limitation."
"The configuration part of the product is an area with certain shortcomings where improvements are required."
"Nasuni provides enough reporting to see what's happening. You can see the number of shares, total volume, issues, conflicts, etc., but it doesn't provide much visibility from a content perspective. For example, it doesn't tell you the data age. When you're trying to sort and filter information, the data creation date is a critical factor. Nasuni doesn't give you that. You can't get a count of all the file types, like the number of PDFs, Word docs, and PPT files."
"We can recover if data and a Filer are lost because of a possible ransomware event, but even that takes time to recover."
"The only thing that I'd like to see is more support for platforms like OneDrive or Box.com."
"Nasuni recently implemented a health system for filers. However, it needs better visibility because it lacks data and an explanation, or reasoning as to why a particular filer may be unhealthy."
"We would like to have a user desktop agent to help improve the end-user experience."
"Some applications may not be suited for the Nasuni environment. You may need something with better performance. Otherwise, if you want to run daily operations or some file system, it's a good bet."
"Nasuni is not a stable solution."
"One area that we've recently spoken to Nasuni about is single sign-on."
 

Pricing and Cost Advice

"I would rate it a seven out of ten for pricing. It could be improved."
"Pure Storage is expensive. It comes with features, so you get what you pay for. It is expensive compared to our old storage systems, but from the amount of human effort that you have to pay to babysit a storage system, it reduces that. I don't know if the TCO is reduced, but it's not a concern for us."
"Pure came in at a better price point than EMC and performed better than Compellent."
"We have 16 or 18 arrays. We like to do the three-year support model so that we get Evergreen and therefore, we get free upgrades. We pay around more than 1.5 million dollars."
"No storage device is cheap, but Pure Storage is fairly priced and offers what you pay for. You get all the licenses in the future when you purchase a license."
"It is cheaper than NetApp."
"Its price is almost double than any other flash storage solution."
"We have seen a reduction in TCO."
"The price falls within the mid-range, neither inexpensive nor high-priced."
"It is not a cheap product."
"I would not say it is economically priced, but it is affordable. If you can afford to pay for it, it is worth the money, but it is definitely not overpriced. It is priced about where it needs to be in the market. We were satisfied with the way they did their licensing and how they handled it. I believe they actually license by data size. It is based on how much data is being held on the machine and replicated, and that's completely understandable. So, for us, their pricing was as expected and affordable."
"With this solution, the license renewal is pretty swift. With the virtual appliance, you just need to take care of the OS versions and patches. In a way, we don't have to struggle much with renewals because the only thing that we need to take care of are the licenses. We renew it every three years. This aspect goes with infrastructural costs because it doesn't cost us too much to maintain the solution."
"Its pricing can get a tad expensive. When we first took Nasuni out, we were just paying for the service. We got storage at a reduced rate. It has now changed, and they're now more of an all-in-one type of thing. It can be quite expensive, but it works out. Apart from that, licensing-wise, it's very simple."
"It's cheaper than a lot of alternatives but it's not cheap."
"The cost of licensing is negotiated and billed annually per terabyte."
"The pricing is on par with everybody else, and fair."
"There are annual costs that we pay for maintaining all of the snapshot history in the cloud. That is the primary cost that we pay. We occasionally buy newer Nasuni appliances or deploy them to new offices when the need occurs. That capital equipment expenses is less than the cost of buying new file storage systems. For the most part, you are trading a CapEx cost of storage equipment for an OpEx cost for management of all the snapshot data in the cloud."
"It has a license fee as well as hardware costs, which we would incur if we want to use Nasuni Cloud Storage Gateway for upgrades."
